Bouncing front passenger tire.

Hi everyone. New member, LOVE this site. It helped me fix my ambient temp sensor. So much good info I decided to join. Thanks for having me.

CAR INFO:

2001 525i
230k miles
2nd owner, bought it from original owner with 208K miles.

Car has been AWESOME!!

Todays problem:
I've noticed that eveytime I hit a small pothole or uneven pavement I can hear and feel what I can only desribe as sounding like the tire is literally "bouncing" up and down inside the fender well like a ball on the road and shakes the steering wheel. Other than hitting bumps/potholes/railroad tarcks, car rides great and tracks well. No shaking under braking unless I hit a bump at the same time as applying the brakes.

Any info is GREATLY appreciated!!

Thanks, Jimmyb

Yup. A proper strut will rebound only once. When it goes bad, it will rebound more than Dennis Rodman in his hay days.

Although most likely a failed strut, it could also be a failed ball joint. At that mileage, a complete front end replacement would be advised. It would restore your ride and handling to like new. The parts are $1200 + labor. It all depends on how long you plan to keep this car.

Thanks for the answers, Dennis Rodman LOL. Good one. When replacing the strut, what parts should be replaced? Just the strut or are there other parts?

Thanks, Jimmyb

It sound like how my bad tie rod ball joint acts. Before you buy parts, jack it up and see if the wheels have any side to side play.

+1 on the suspension refresh. You'll be amazed.

I would do upper and lower control arms, tie-rod ends, ball joints (if needed), maybe upgrade your sway bar and do the end links while you're in there. Koni makes a great shock, as does Bilstien. If you haven't already, it's probably time for wheel bearings (if you are experiencing noise).

I must ask if it's brake related (at slow speed on bumps)?

If so, read this:

No, not brakes. They work great. Only "bounces" when hitting pothole.

It's difficult to interpret "and shakes the steering wheel" since a bump will often result in a little tremour on the steering wheel, although not what I would call a shake. But then that's the challenge of language isn't it? Just as my "fair & reasonable" is someone else's "extreme & one sided."
Also when you mention "sounding like the tire is literally "bouncing" up and down " do you mean several/many bounces or one/two.

It's just possible that one or both sway bar links are bad and generating the noise when you hit a bump, especially if the bump/pothole is on one side only. If so, you would hear a quick click-click, maybe a third click. Which some may describe as a clunk.

However, unless you have reason to believe that the previous owner refreshed the front suspension before you bought the car, all the recommendations above regarding struts and links are right on the money. At 200k+ miles, the car is way overdue if those parts are original.

The "bouncing" only occurs on the right side when I hit a hole or large bump It literally feels and sounds like the tire is bouncing down the road afte hitting the bump. It also shakes the steering wheel. All is fine on the road other than that, drives and rides great when I'm not hitting bumps.

Not sure what the previous replaced or repaired on the front end. I've had the car for about 18 months and this just started about a month ago. Car has been AWESOME.

For a good DIY with parts list see:

I recently did this. Huge difference! Not too hard other than removing the three ball joints.
